WIND-CHEST FOR ORGANS.

SPECIFICATION forming part of Letters Patent No. 457,686, dated August 11, 1891.

Application filed February 12, 1891. Serial No. 381,216. (No model.) Patented in Switzerland July 10, 1890, No. 2,445 i in France Julyr 15, 1890, No. 206,983, and in Belgium November 19, 1890,1To. 92,785.

To @ZZ whom it may concern.-

Beit known that I, CARL Go'rTLiEB WEIGLE, a subject of the King of Vrtemburg, residing at Stuttgart, Kingdom of lViirtemburg, German Empire, have invented certain new and useful lmprovementsin Vind-Ohests for Organs, (for which 1 have obtained patents in Belgium, dated November lf), 1890, No. 92,785; in France, dated July l5, i890, No. 206,983, and in Switzerland, dated July l0, 1890, No. 2,445 of which the following is a specification.

This invention has [or its objectthe rcmoval of several complicated mechanisms of the former mechanical and pneumatic tube construction of organs It relates principally to the construction of the wind-chest and the coupling arrangement at the manual or key-board. The wind-chest is made of the simplest construction for pneumatic wind-chests so far known, since no Vents, rods, stickers, bellows, eccentric rollers, or the like occurtherein; but for the windclosure ot' the pipe-openings and register channels there are only employed membranes of rubber cloth treated with oil or leather membranes which are made wind-tight. Mechanisms which are affected by the weather are thus entirely abolished by my new windchest. The couplings are characterized by verticallyhanging vents, which are pressed rmly to their seats by means of stickers and membranes actuated from one side only by thev wind of the organ. In the annexed drawings these arrangements are illustrated.

Figure l shows the coupling arrangement sectioned along a: 0c, Fig. Fig. 2 is a section along y y, Fig. l. Fig. 3 is a plan View of the wind-chest sectioned along .e 2, Fig. a. Fig. 4 is a section along u n, Fig. Fig. 5 is a section along c c, Fig. 4. Fig. is aseotion along` w w, Fig. a.

By depressing a key of the iirst manual the pull-wire Z Fig. 2, is actuated, and thereby the vent Sp V is opened. The wind from the bellows, guided into the channel A, passes through the opening and the tube l to the space B (shown in Fig. l) and presses up the rubber or leather membrane M4, glued over wire D, raises the double vent E, and thereby closes the opening S, so that the wind in channel F can no longer pass through G into H. As long as the vent E rests on the opening T, the wind flows from F through S and G into the channel H. As soon as the proper registers are drawn the organ wind enters the double channel J, Fig. Ll, belonging to one register, and the single channel K, belonging to another register. The double channel is intended for a register with large pipes-such as base, principal, or the like-and the single register-channel is for voices with slight consumption of wind. The spaces J and K, as also the openin gs L and N, are separated from the channel Il by means of the square membranes M5 and M, glued fast at their edges, but left free at their centers, Figs. 4, 5, ando.

As long as the vent E rests on the opening T t-he wind passing from F through S and G to ll presses the membranes hl5 and M against the openings L and N, so that wind in the register-channels J and K is entirely shut off from the openings L and N; but when the double vent 'E closes the opening S the wind in channel lfl can escape throughGand T. The wind in J and K now presses the membranes Mil and hlG away from the openings L and N, Hows into the latter, and causes the pipes Pf and Pf2 to speak or sound. As soon as the vent E sinks again and closes T, the wind entering through S and G to H presses the membranes once more against the openings L and N.

The object of the couplings in Figs. l and 2 is that when a pedal key is pressed thereis a contemporaneous sounding of the homonymons tones in the first or second manual, or when a key in the first manual is depressed there is a contemporaneous sounding of the analogous tone of the second or third manual.

The arrangement in the pedal is in substance exactly the same as in the manual. Under the pedal key-board there is a channel, as in Fig. 2, with vents. By depressing a pedal key the corresponding vent is opened, as in Fig. 2, and the wind passes through a tube to a pedal-chest constructed as in Fig. it, and at the same time through a second tube P, Fig. 2,

5o the ring O, which membrane, by means ot into the space Y, which at the left roo is closed by vent V and at the right by vent V2. Op is the coupling from the first .manual to the pedal, and C192 the coupling from the second manual to the pedal. When the coupling-stops are not drawn, the wind in the spaces H H2 H3, by means of the membrane M M2 M3, presses the stickers Si', Si?, and Sig so firmly against the Vents V V2 V3 that the Wind entering from the pedal into Y cannot press the vents away. If the coupling from the irst or second manual to the pedal is drawn, the wind can escape from channel H or H2 and the wind in Y presses vent V or V2 away and flows through tube I or I I tothe Wind-chest of the rst or second manual. There is the same construction for the coupling Op and @p2 from the rst to the second manual. The vents V', V2, and V3 prevent the wind escaping from tube I, no matter if a coupling is drawn or not. The pull-wire Z2 is actuated and the vent Sp V2 opened by a key of the second manual. The wind passes through opening and tube I to the wind-chest ofthe second manual, constructed the same as shown in Fig. 4. In the case of a third and fourth manual the construct-ion is in substance the same.

lVhat I claim as new, and desire to secure by Letters Patent, is-

The combination, in an organ, of the windchannel F, having the upper and lower windopenings S and T, the double vent-Valve E, controlling both wind-openings, the rod D, secured to the double vent-valve, the chamber B, the membrane M4, arranged over said chamber and connected with the rod, the tube I, the registerchannels J K, the pipe-tubes L N, the membranes M5 and M, controlling` the lower ends of the pipe-tubes, and the channel G, leading from a point between the upper and lower wind-openings S and T to the under side of the membranes controlling the pipe-tubes, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
